AbstractPrevious epidemiological studies on the associations between polyunsaturated fatty acids (PUFAs) and cancer incidence have been inconsistent. We investigated the associations of plasma omega-3 and omega-6 PUFAs with the incidence of overall and 19 site-specific cancers in a large prospective cohort. 253,138 eligible UK Biobank participants were included in our study. With a mean follow-up… Continue reading Associations of plasma omega-6 and omega-3 #fatty acids with overall and 19 site-specific #cancers: A population-based cohort study in UK Biobank
Once-Weekly #Semaglutide in Persons with #Obesity and #Knee Osteoarthritis
BackgroundWeight reduction has been shown to alleviate symptoms of osteoarthritis of the knee, including pain. The effect of glucagon-like peptide-1 receptor agonists on outcomes in knee osteoarthritis among persons with obesity has not been well studied.MethodsWe conducted a 68-week, double-blind, randomized, placebo-controlled trial at 61 sites in 11 countries. Participants with obesity (a body-mass index… Continue reading Once-Weekly #Semaglutide in Persons with #Obesity and #Knee Osteoarthritis
#Pistachio Consumption Increases #Macular Pigment #Optical Density in Healthy Adults: A Randomized Controlled Trial
BackgroundPistachios are a bioavailable source of the xanthophyll lutein. Along with zeaxanthin, these plant pigments are major components of macular pigment (MP) in the human retina. MP can be non-invasively measured and is referred to as MP optical density (MPOD). MPOD is modifiable with dietary interventions that include lutein and zeaxanthin (L/Z). Higher MPOD protects… Continue reading #Pistachio Consumption Increases #Macular Pigment #Optical Density in Healthy Adults: A Randomized Controlled Trial
Skewed epithelial cell differentiation and premature aging of the thymus in the absence of vitamin #D signaling
Central tolerance of thymocytes to self-antigen depends on the medullary thymic epithelial cell (mTEC) transcription factor autoimmune regulator (Aire), which drives tissue-restricted antigen (TRA) gene expression. Vitamin D signaling regulates Aire and TRA expression in mTECs, providing a basis for links between vitamin D deficiency and autoimmunity. We find that mice lacking Cyp27b1, which cannot… Continue reading Skewed epithelial cell differentiation and premature aging of the thymus in the absence of vitamin #D signaling
Association of Self-Reported #Sleep Characteristics With Neuroimaging Markers of Brain #Aging Years Later in Middle-Aged Adults
ObjectivesTo determine the association between early midlife sleep and advanced brain aging patterns in late midlife.MethodsUsing the CARDIA study, we analyzed sleep data at baseline and 5 years later, focusing on short sleep duration, bad sleep quality (SQ), difficulty initiating and maintaining sleep (DIS and DMS), early morning awakening (EMA), and daytime sleepiness. These were… Continue reading Association of Self-Reported #Sleep Characteristics With Neuroimaging Markers of Brain #Aging Years Later in Middle-Aged Adults
Dietary pro-oxidant therapy by a vitamin #K precursor targets PI 3-kinase VPS34 function
In light of emerging evidence that antioxidants can have cancer-promoting effects, Swamynathan et al. tested potential pro-oxidant interventions (see the Perspective by Pannia and Dowling). In particular, the authors focused on menadione sodium bisulfite, a water-soluble precursor of vitamin K. As the authors anticipated, this menadione derivative suppressed prostate cancer growth. The researchers then examined… Continue reading Dietary pro-oxidant therapy by a vitamin #K precursor targets PI 3-kinase VPS34 function
Associations of #semaglutide with first-time diagnosis of #Alzheimer’s disease in patients with type 2 diabetes: Target trial emulation using nationwide real-world data in the US
INTRODUCTIONEmerging preclinical evidence suggests that semaglutide, a glucagon-like peptide receptor agonist (GLP-1RA) for type 2 diabetes mellitus (T2DM) and obesity, protects against neurodegeneration and neuroinflammation. However, real-world evidence for its ability to protect against Alzheimer's disease (AD) is lacking.METHODSWe conducted emulation target trials based on a nationwide database of electronic health records (EHRs) of 116… Continue reading Associations of #semaglutide with first-time diagnosis of #Alzheimer’s disease in patients with type 2 diabetes: Target trial emulation using nationwide real-world data in the US
Sex-specific alterations in pulmonary metabolic, xenobiotic and lipid signalling pathways after #e-cigarette aerosol exposure during adolescence in mice
Background E-cigarette use is now prevalent among adolescents and young adults, raising concerns over potential adverse long-term health effects. Although it is hypothesised that e-cigarettes promote inflammation, studies have yielded conflicting evidence. Our previous work showed that JUUL, a popular e-cigarette brand, elicited minimal lung inflammation but induced significant molecular changes in adult C57BL/6 mice.Methods… Continue reading Sex-specific alterations in pulmonary metabolic, xenobiotic and lipid signalling pathways after #e-cigarette aerosol exposure during adolescence in mice
A single bout of physical #exercise improves 1-hour post-load plasma #glucose in healthy young adults
PurposePhysical exercise is a key component in the treatment of type 2 diabetes and plays an important role in maintaining a healthy glucose metabolism even in healthy subjects. To date, no studies have investigated the effect of a single bout of aerobic physical exercise on glucose metabolism in young, moderately active, healthy adults.MethodsWe performed an… Continue reading A single bout of physical #exercise improves 1-hour post-load plasma #glucose in healthy young adults
